Abstract
A vacuum switching apparatus for automatically performing a series of breaking and disconnecting operations includes a fixed electrode and a movable electrode mounted in a vacuum vessel. The movable electrode is sequentially movable between a closing position, an opening position and a disconnecting position. After the movable electrode passes through the opening position located between the closing position and the disconnecting position, the between-electrode opening speed of the movable electrode is reduced by a decelerating means. With this configuration, it is possible to move the movable electrode from the closing position to the disconnecting position without lowering the breaking performance, and hence to automatically perform a series of breaking and disconnecting operations.
